beallowedoutoftheschool,unlessaccompaniedbyhisorherownparents.A.should
B.mustC.shall
D.can參考答案:C【詳解】考查shall的特殊用法。句意:根據(jù)學(xué)校規(guī)定,除非有親生父母陪同,否則不得讓任何兒童離開學(xué)校。A.should意為“按理說,應(yīng)該,竟然”;B.must意為“必須,偏偏,非要”;C.shall用于第二和第三人稱的陳述句時(shí),有“警告、命令、威脅、允諾”等;D.can有“可能,可以”之意。分析語境可知,本句中含有命令或警告的意思,即如果不是親生父母,誰也不得帶走兒童,所以從語氣來說,應(yīng)該選C項(xiàng)?!军c(diǎn)睛】Shall作為助動(dòng)詞,一般用于第一人稱Ⅰ和We,表示一個(gè)將來的動(dòng)作,構(gòu)成將來時(shí)態(tài)。Shall后面接動(dòng)詞原形。例如:(1)IshallthinkitoverandLetyouknowmyidea.我將考慮一下此事,然后告訴你我的想法。(2)Weshallhaveagoodtimeinthepark.我們?cè)诠珗@里會(huì)玩得很高興的。1.Shall用于第一人稱,表示征求對(duì)方的意愿。如:Whatshallwedothisevening?我們開始上課好嗎?2.Shall用于第一、第三人稱疑問句中,表示說話人征求對(duì)方的意見或向?qū)Ψ秸?qǐng)示。如:Shallwebeginourlesson?Whenshallhebeabletoleavethehospital?他什么時(shí)候能出院?3.Shall用于第二、第三人稱,表示說話人給對(duì)方命令、警告、允諾或威脅。如:Youshallfailifyoudon'tworkharder.如果你不加倍努力,你會(huì)失敗的。(警告)HeshallhavethebookwhenIfinishreading.我讀完后,他會(huì)得到那本書(允諾)Heshallbepunishedifhedoso.如果他再這樣做,必將受到處罰。(威脅)14.Themoviewas

A.made
B.designed
C.intended
D.supposed參考答案:C略15.Iftheproject________beforetheendofthismonthisdelayed,theconstructioncompanywillbefined.A.completed
B.beingcompletedC.tobecompleted
D.completing參考答案:C考查非謂語動(dòng)詞。從語境可以看出,如果建筑工程被耽擱的話,建筑公司將被罰款,所以工程應(yīng)當(dāng)是正在被建,將要被完成。所以要用動(dòng)詞不定式tobecompleted...短語作定語。故選C。16.Busywiththeirbusiness,theyhadnotimeto______theirwedding,sotheyhaditorganizedbyacompany.A.accelerateB.arrangeC.approveD.acknowledge參考答案:B試題分析∶考查動(dòng)詞。句意是他們沒有時(shí)間安排婚禮。A.accelerate促進(jìn);增加;B.arrange安排;C.approve贊同;D.acknowledge意識(shí)到。故選B。17.Thenaturalenvironmentshouldbeprotectedbecauseoftheimportantrole_______playsinhumansurvivalanddevelopment.A.which
B.theone
C.it
D.that參考答案:C考查代詞。句意:自然環(huán)境應(yīng)該被保護(hù),因?yàn)樗谌祟惿婧桶l(fā)展方面起著重要作用。此處用it指代Thenaturalenvironment,在從句中作主語,it用于替代上文出現(xiàn)的同一事物,所指的是同名同物;one用于替代上文提到的可數(shù)名詞單數(shù),表示泛指;that用于替代上文出現(xiàn)的可數(shù)名詞單數(shù)或不可數(shù)名詞,表特指。one和that所指的是同名異物。不能用which,如果是which的話,那構(gòu)成定語從句,先行詞是role,但這不符合語境。故只能選C。18.________physicalexaminationisamustinmanycompanies.A.Common B.Regular C.Normal D.Ordinary參考答案:B略19.Hot_______thenightairwas,wesleptdeeplybecauseweweresotiredafterthelongjourney.
A.although
